The e4 Smart Shaft consists of a uniform central shaft of variable length and individualized end pieces.
The rotor shaft is part of the drive train and is directly connected with the rotor. It serves the purpose of forwarding rotational movements and torque, and of bearing rotating parts.
This Felss rotor shaft offers minimization of wall thicknesses in the area of power transmission and optimal material distribution along the functional external contour. The lightweight design solution ensures a considerable reduction of weight of 50%. This is made possible by the intelligent interaction of various cold forming processes for a high level of functional integration. The Felss rotor shaft means economical and reliable complete production of components.
50% lighter in comparison with chipping processing.
50% component strength increase (material compression is the physically false expression).
70% more resource efficient due to chipless processing.
